Atmospheric CO2 concentrations (ppm) derived from in situ air measurements at Mauna Loa, Observatory, Hawaii. Credits: Dr. Pieter Tans ( NOAA/ESRL ), Dr. Ralph Keeling, S. J. Walker, S. C. Piper and A. F. Bollenbacher ( Scripps Institution of Oceanography ) 2013 The diagram shows the concentration of CO2 (carbon dioxide) in the atmosphere as parts per million (ppm) 1960-2012. In 1960 the figure was 317 ppm and in 2012 it was 394 ppm. The annually updated figure is included in the latest version of ClimatePositions with impact on the national Climate Atmospheric carbon dioxide (CO2) concentration will soar past a scary threshold this year, exceeding 417 parts per million (ppm) — a 50% increase since the start of widespread industrial activity 2021-04-06 · When the National Oceanic and Atmospheric Administration (NOAA) research station "began collecting CO2 measurements in the late 1950s, atmospheric CO2 concentration sat at around 315 PPM," the Washington Post reported. "On Saturday, the daily average was pegged at 421.21 PPM—the first time in human history that number has been so high." The magnitude of present-day equatorial upwelling, however, is represented by a seawater CO 2 enrichment in the western equatorial Atlantic by approximately 30 ppm—about 9% deviation from atmosphere–seawater equilibrium . As recently as 1910, atmospheric CO2 stood at 300 ppm – higher than it had been for some 800,000 years at least – but jumped up another 100+ ppm over the next century as pollution levels skyrocketed. Obviously, crossing 400 ppm was a huge symbolic moment, numerically at least, but the symbolism doesn't end there.

CO2 peaks in May every year. NOAA reported that the global average of atmospheric CO2 hit 412.5 parts per million (ppm) in 2020, a rise of 2.6 ppm from 2019, the fifth-largest increase since they began measuring atmospheric This figure shows concentrations of carbon dioxide in the atmosphere from hundreds of thousands of years ago through 2015, measured in parts per million (ppm). The data come from a variety of historical ice core studies and recent air monitoring sites around the world.

The reason why it's acceptable to use Mauna Loa as a proxy for global CO2 levels is because CO2 mixes well throughout the atmosphere. Consequently, the trend in Mauna Loa CO2 (1.64 ppm per year) is statistically indistinguishable from the trend in global CO2 levels (1.66 ppm per year). 2020-06-10 · However, as the yearly May benchmark was released it appears to have done little to slow the ever-increasing rise in carbon dioxide in the atmosphere. May 2020 hit a record high, 417 parts per The magnitude of present-day equatorial upwelling, however, is represented by a seawater CO 2 enrichment in the western equatorial Atlantic by approximately 30 ppm—about 9% deviation from atmosphere–seawater equilibrium . CO2 and Past Climates As a point of reference, pre-industrial CO2 levels were around 280 parts per million (ppm) and today, we stand at 410ppm. The most distant period in time for which we have estimated CO2 levels is around the Ordovician period, 500 million years ago.

Se flikarna nedan för mer information och CO2 avläsningar. CO2.Earth förbinder allmänheten med de senaste uppgifterna och informationen för att stabilisera jordens atmosfär, klimat och levande miljöer. I maj 2013 uppmättes för första gången dygnsvärden på över 400 ppm (miljondelar).

At the time, atmospheric CO2 concentration was at a whopping 3000 to 9000 ppm! In 2013, CO 2 levels surpassed 400 ppm for the first time in recorded history. This recent relentless rise in CO 2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air. 2021-04-08 · NOAA reported that the global average of atmospheric CO2 hit 412.5 parts per million (ppm) in 2020, a rise of 2.6 ppm from 2019, the fifth-largest increase since they began measuring atmospheric 2019-05-12 · For the first time in human history — not recorded history, but since humans have existed on Earth — carbon dioxide in the atmosphere has topped 415 parts per million, reaching 415.26 parts per 2018-05-02 · Prior to the onset of the Industrial Revolution, CO2 levels had fluctuated over the millennia but had never exceeded 300 ppm at any point in the last 800,000 years.
